英文摘要	The hole-mediated magnetism in mn-doped gan nanowires is investigated using the k (.) p method and the mean-field model. the curie temperature (t-c) as a function of the hole density p can be explained based on the calculated band structure of the nanowires. for low mn concentration, t-c vs. p shows many peaks stem from the peaks of the one-dimensional density of states. when the mn concentration is increased, t-c is enhanced, and the peaks of t-c versus p are fully merged by the thermal distribution of the holes in the valence band. it is found that the curie temperature in mn-doped gan wire can be higher than room temperature, in agreement with experiment [song et al., j. phys.: condens. matter 17, 5073 (2005)]. the ferromagnetism in mn-doped gan wire is slightly anisotropic due to the small spin-orbit coupling.
